Hi,

There is no /boot on the floppy, all the files
(syslinux.cfg,vmlinuz,initrd.img,boot.msg,Ldlinux. sys) are at the root. So I
tried copying initrd.img to /boot on the hd (/ is /dev/hdb6), renaming
intird-2.4.20-8.img (which must be the buggy kernel) to
intird-2.4.20-8.old.img and renaming initrd.img (from the floppy) to
intird-2.4.20-8.img. i checked grub.conf, it was pointing to the right
place, so it looked ok. But when I rebooted I had the same error as usual,
that is "Kernel Panic: VFS: Unable to mount root fs on 00:00" or something
close to it. i searched on google and find those possible reasons for the
error:
1. You passed the kernel the wrong root drive.
2. The File system is not supported by the kernel.
3. The file system driver is compiled as a module and you are not using a
proper initrd.
4. Fine system is corrupt, whoops.

but if I can boot from the floppy then the kernel is right, so why won't it
boot when I put it on the HD?

Also someone suggested to me to do that:
boot from floppy,
insert your installation CD
copy the kernel-2.4.20-8.rpm file to your harddisk
rpm -e --nodeps kernel-2.4.20-8
rm -rf /lib/modules/`uname -r`
rpm -i kernel-2.4.20-8

and said it's really risky, is it really?

Thanks

Well,

At this point I'd say that is as good as option as any, it does have
some risk to it. When you boot off the linux install disk go into
rescue mode then chroot (it tells you how to do it during the rescue
session) so your system is the root system. The CD should be mountable
at that point so you can do the install.
